Allow user to choose install path. Allow user to UNDO a disabling of a service in the 'System Advisor' section (perhaps you could show the service as greyed out when disabled but don't make it disappear altogether which is what happened!).
I agree; the 'disable service' (blue link) is a duplicate action for selecting option using check-box and 'Fix problems' -- but cannot be undone. However, using the check-box / 'Fix' option allows restoring.
